Fault Tectonics in the Yukon North Slope Rapid Depression

Mesozoic to Tertiary rocks in the Rapid depression on the Yukon North Slope are dissected by a N-NNE striking fault array. The dataset likely contains structural analysis of two phases of Tertiary deformation, characterized by strike-slip displacements and contraction regimes. It was published by the Government of Yukon and last updated on April 17, 2026.

Use Cases

• Model fault displacement patterns based on sinistral and dextral strike-slip descriptions.
• Analyze tectonic stress regimes based on W-E to NW-SE contraction features.
• Map subsurface structural heterogeneity based on interpretations of older reactivated faults.
• Validate regional tectonic models based on comparisons to large-scale strike-slip fault zones like the Kaltag fault.

Strengths

• Data is sourced from a government geological survey (Government of Yukon).
• The description details specific deformation phases (D1 and D2) and structural styles.
• Last updated date is explicitly provided (2026-04-17).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the Yukon North Slope region.
